Indeed, "Crisis de Identidad..." is a remix to a track from 1993 by Deus ex Machina (http://www.deusexmachina.com.mx) wich originaly was in an industrial style. The remix I did was inspired by the Depeche Mode "songs of faith and devotion" style and also by Recoil and the Gary Numan from the nineties.
By the way, I didnt use any sample from Depeche mode, although the starting piano is of course a reference to "walking in my shoes"
